I bet those Blue Rino tanks that you trade in your empty for the full
ones are by some other method. YOu think you get a full tank, but they
only fill it part of the way even counting on that required 'gas space'.
I bet many think the tank is totally full of the propane, or should be.

They have to stop filling when the OPD device shuts off, but that's more
than 15 pounds. The Blue Rhino tank I got filled held 19 pounds. A new
tank I bought at the same time (not from an exchange place) held 20
pounds. The price of the fill was about the same as a Blue Rhino
exchange, but I mot more propane for that.
